Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC fixes from Olof Johansson:
 "A series of fixes (and in some cases, some cleanups):

  Via Tony Lindgren:
   - A collection of OMAP regression fixes, in particular because
     firmware no longer sets up all pin states before starting the
     kernel.
   - cpufreq fixes for OMAP (Rafael is on vacation and this was
     pre-agreed).
   - A longer series of misc regression fixes and cleanups, warning
     removals, etc for OMAP

  From Arnd Bergmann:
   - A series of warning fixes for various platforms (defconfig builds)

  Misc:
   - A couple of tegra fixes, one for i.MX, some vt8500 fixes, etc."
